SANITARY PIPE-STEM.

Specication oi' Letters Patent.

Patented Nov. 17', 1908.

Application lcd April 22, 1908. Serial No. 428,487.

To all whom it may concern:

Be it known that we, J oHN J. Gor'rsoimmi a resident of Taunton, in the county of Bristol and State of Massachusetts, and BURTON W. PI-IELIS, a resident of Providence, in the county of Providence and State of Rhode Island, both citizens of the United States, have invented a new and Improved Sanitary Pipe-Stem, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a stem adaptable to any pipe and so constructed as to form within the stem a reservoir for the collection of saliva and the reception of foreign substances, preventing such factors collecting in the bowl of the pipe or its stem except in said reservoir.

It is a further purpose of the invention to so construct the stem that it will be sanitary and so that it may be adapted to any character of bowl.

The invention consists in the novel construction and combination of the several parts, as will be more fully hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of a smollng pipe having the improved stem applied; Fig. 2 is a longitudinal section throu h the improved sanitary stem disconnecte from the bowl of the pipe; Fig. 3 is a side elevation of the inner tube of the stem, located mainly in the reservoir thereof; and Fig. 4 is a lon 'tudinal section through a slightly modifie form of the improved stem.

The improved stem is adapted to be introduced in an air-tight manner into the stem extension A from the bowl Bof a tobacco pipe of any desired shape and character. The bore 10 of the said stem extension A is tapered at its outlet end, and at said end recelves the outer end portion of the improved sanitary and detachable stem C, having integral therewith or detachable therefrom a suitable mouthpiece 11. In the drawings, the mouthpiece 11 is shown integral with the auxiliary stem. This auxiliary stem C is enlarged diametrically at its outer end, or the end that is ada ted to enter and is fitted to the main stem connected directly with the bowl B, and is correspondingly tapered to the interior taper at the outlet end of said main stem, as is shown in Fig. 1, the ta ered portion of the auxiliary stem being esignated as 12.

The outer tapered end of the auxiliary or improved stem is enlarged and its bore is increased diametrically over that of the bore 13 in the mouthpiece section 11, to provide a chamber or reservoir 14 for the reception and retention of saliva and particles drawn from the bowl B of the pipe when the pipe is in use.

The reservoir 14 may be of any desired dimensions and receives an inner or distributing tube D, that extends beyond its outer end and practically to its inner or mouthpiece end.

The distributing tube D is provided with an outer plug terminal section 15 that closes the outer end of the reservoir when the tube is properly inserted therein, as is shown in Fig. 1. The outer end of the said plug section 15 is of less diameter than that of the bore of the main stem A into which it eX- tends, as is also shown in Fig. 1, and that portion of the plug section 15 of the distributing tube D that extends beyond the outer end of the auxiliary stem C is provided with an annular roove 16, constituting an air vent that facilitates the draft and the leading of the saliva and particles drawn from the bowl B to the reservoir 14. The inner end of the distributing tube D is a blind end, being suitably closed, as is shown at 17 in Figs. 2, 3 and 4, and adjacent to this blind end 17 of said distributing tube one or more, usually two, apertures 18 are produced, permitting the smoke drawn into said tube to pass to the mouthpiece section of the auxiliary stem C, while the saliva and accompanying particles find lodgment in said reservoir 14.

The auxiliary stem C is held, preferably by frictional engagement, in the main stem A, but the engagement may be otherwise effected, and the distributing tube D may be 'held in the auxiliary stem C by frictional contact, as is shown` in F ig. 2, or a screw connection may be elfected, as illustrated at 19 in Fig. 4.

The auxiliary stem C may be readily disengaged from the main stem A, and should any matter lodge in the main stem it can be readily removed therefrom, and upon removing the distributingl lube D from the reservoir lelthe latter may be readily and quickly cleaned.

Ample space is provided between the blind end of the distributing tube D und the wall of the reservoir 14, to permit the ready pas sage of smoke to the mouthpiece Section of the auxiliary stein.

Having thus described our invention, we cluiin as new and desire to secure by Letters Patent:

The combination with the bowl of a pipe und the stem extension, of a shove bit mouth piece havin in its inner end a longitudinal l5 recess, forinmg a reservoir and communicating with the bore of the mouth piece, I(1nd :i distributing tube extending into the recess, the inner end of the tube being closed and flanged laterally, said end being of smaller diiuneter than the reeeSs, the tube being provided with side openings, and having an annular groove at its outer end portion.

In testimony whereof we have Signed our naines to this Speeiiieation in the presence of two subscribing witnesses.
